<h4><a name = "tag_001_014_1707">&nbsp;</a>NAME</h4><blockquote>
pcat - expand and concatenate files (<b><a href="intro.html#tag_001_003_003">LEGACY</a></b>)
</blockquote><h4><a name = "tag_001_014_1708">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

pcat <i>file</i>...
</code>
</pre>
</blockquote><h4><a name = "tag_001_014_1709">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>pcat</i>
utility unpacks files in the format used by
<i><a href="pack.html">pack</a></i>
and writes the unpacked form to standard output.
For each
<i>file</i>
operand, a file named
<i>file</i><b>.z</b>
(or just
<i>file</i>,
if
<i>file</i>
ends in
<b>.z</b>)
is unpacked.
<p>
A file is not written in its unpacked form if:
<ul>
<p>
<li>
The file cannot be opened.
<p>
<li>
The file does not appear to be the output of
<i><a href="pack.html">pack</a></i>.
<p>
</ul>
</blockquote><h4><a name = "tag_001_014_1710">&nbsp;</a>OPTIONS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_001_014_1711">&nbsp;</a>OPERANDS</h4><blockquote>
The following operand is supported:
<dl compact>

<dt><i>file</i><dd>A pathname of a file to be
<i>pcat</i>ed;
<i>file</i>
can include or omit the
<b>.z</b>
suffix.

</dl>
</blockquote><h4><a name = "tag_001_014_1712">&nbsp;</a>STDIN</h4><blockquote>
Not used.
</blockquote><h4><a name = "tag_001_014_1713">&nbsp;</a>INPUT FILES</h4><blockquote>
The input files are regular files
in the format produced by the
<i><a href="pack.html">pack</a></i>
utility.
</blockquote><h4><a name = "tag_001_014_1714">&nbsp;</a>ENVIRONMENT VARIABLES</h4><blockquote>
The following environment variables may affect the execution of
<i>pcat</i>:
<dl compact>

<dt><i>LANG</i><dd>Provide a default value for the internationalisation variables
that are unset or null.
If
<i>LANG</i>
is unset or null, the corresponding value from the
implementation-dependent default locale will be used.
If any of the internationalisation variables contains an invalid setting, the
utility will behave as if none of the variables had been defined.

<dt><i>LC_ALL</i><dd>
If set to a non-empty string value,
override the values of all the other internationalisation variables.

<dt><i>LC_CTYPE</i><dd>
Determine the
locale for the interpretation of sequences of bytes of text data as
characters (for example, single- as opposed to multi-byte characters
in arguments).

<dt><i>LC_MESSAGES</i><dd>
Determine the locale that should be used to affect
the format and contents of diagnostic
messages written to standard error.

<dt><i>NLSPATH</i><dd>
Determine the location of message catalogues
for the processing of
<i>LC_MESSAGES .
</i>
</dl>
</blockquote><h4><a name = "tag_001_014_1715">&nbsp;</a>ASYNCHRONOUS EVENTS</h4><blockquote>
Default.
</blockquote><h4><a name = "tag_001_014_1716">&nbsp;</a>STDOUT</h4><blockquote>
The standard output
is the concatenation of the unpacked files identified by the
<i>file</i>
operands.
</blockquote><h4><a name = "tag_001_014_1717">&nbsp;</a>STDERR</h4><blockquote>
Used only for diagnostic messages.
</blockquote><h4><a name = "tag_001_014_1718">&nbsp;</a>OUTPUT FILES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_001_014_1719">&nbsp;</a>EXTENDED DESCRIPTION</h4><blockquote>
None.
</blockquote><h4><a name = "tag_001_014_1720">&nbsp;</a>EXIT STATUS</h4><blockquote>
The following exit values are returned:
<dl compact>

<dt>0<dd>Successful completion.

<dt>&gt;0<dd>An error occurred.

</dl>
</blockquote><h4><a name = "tag_001_014_1721">&nbsp;</a>CONSEQUENCES OF ERRORS</h4><blockquote>
Default.
</blockquote><h4><a name = "tag_001_014_1722">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
The
<i>pcat</i>
utility does for packed files what
<i><a href="cat.html">cat</a></i>
does for ordinary files, except that
<i>pcat</i>
cannot be used as a filter.
<p>
Applications should migrate to the
<i>zcat</i>
utility.
</blockquote><h4><a name = "tag_001_014_1723">&nbsp;</a>EXAMPLES</h4><blockquote>
To view a packed file named
<i>file</i><b>.z</b>
use:
<pre>
<code>
pcat <i>file</i>.z
</code>
</pre>
or:
<pre>
<code>
pcat <i>file</i>
</code>
</pre>
<p>
To make an unpacked copy, called
<b>abc</b>,
of a packed file named
<i>file</i><b>.z</b>
(without destroying
<i>file</i><b>.z</b>
use:
<pre>
<code>
pcat <i>file</i> &gt;abc
</code>
</pre>
